Abstract

Complexes of the type $MLCl_2$, where M = Co(II), Cu(II), Ni(II), Zn(II), Cd(II) and Hg(II) and L is a thiosemicarbazide ligand derived from reaction between naphthofuran-2-carboxyhydrazide and p-chlorophenylisothiocynate (NCClPT)/p-bromophenylisothiocynate (NCBrPT) characterized by elemental analysis, conductance, magnetic susceptibility measurements, UV-Vis, IR, $^1HNMR$, and ESR. The thiosemicarbazide ligands are bidentate by coordinating through the oxygen of the carbonyl group and the nitrogen of the hydrazide residue. Based on the results, we propose structures for all the metal complexes. Both the ligands and their complexes have been screened for their fungicidal and bactericidal activities
